Title: High output mosfet
Inventor: AREKUSANDAA RIDOO
IPC: H01L27/088
Filed: 1993-06-08
Abstract: PURPOSE: To avoid a device failure due to an overcurrent generated in a cell element surrounding an electrode pad by a minority carrier when a high-output MOSFET is in diode mode operation. CONSTITUTION: Base regions 18 and 19 with source regions 31 and 32 are provided at semiconductor wafers 15 and 16, and a large number of cell regions with the edge part of the base regions 18 and 19 as a channel region are provided. A large-area source electrode pad 11 and a large-area base region 20 with far larger interval than an interval A between cell regions are provided. The peripheral part of the large-area source electrode pad 11 is electrically connected to the large-area base region 20 through insulation layers 41 and 42 by a single conductive protrusion 82. An interval B between the peripheral part of the large-area base region 20 and the base region 19 is set to a narrow interval that is approximately the interval A between the cell regions.  A minority carrier generated at the downstream side of the large-area base region 20 is not directed toward a channel region and is collected in the large-area base region 20, thus preventing an overcurrent from being generated in the cell element.

Title: Ultrasonic defoaming device and its method
Inventor: ISHII SHINYA
IPC: B01D19/00
Filed: 1993-07-01
Abstract: PURPOSE:To effectively gather bubbles irrespective of the form and the foam distribution state of a fluid vessel by changing the frequency from a mode of the high order to a mode of the low order by a control computer connected to an ultrasonic vibrator and an ultrasonic sensor housed in the fluid vessel. CONSTITUTION:In a fluid vessel having an arbitrary shape are housed and installed with an ultrasonic vibrator 2 and an ultrasonic sensor 5. And by a command signal by a control computer 6 receiving a signal from the ultrasonic sensor 5, the ultrasonic vibrator 2 is driven with the frequency near the Nth order mode, such as the 10th order mode and the frequency is gradually decreased. And when the frequency of the next 9th order is approached, the pressure amplitude from the ultrasonic sensor 2 is increased to fix the frequency during a certain time T at the resonance frequency of the peak value. During this time, bubbles are gathered at a node 8 of the sound pressure distribution. After T sec, the frequency is further decreased, and the same is repeated in the next mode. With the mode frequency of the lowest order, the bubbles are gathered at a position of the node 8 of the sound pressure distribution.

Title: Type reproducing device
Inventor: NIINO MAKOTO
IPC: G11B20/10
Filed: 1987-06-30
Abstract: PURPOSE:To obtain an audio signal suppressed in its carrier component even in case of a slower tape speed than recording by converting a reproduced RWM signal to a saw tooth signal and holding a sample as well. CONSTITUTION:The peak value of a saw tooth wave signal voltage Vs converted from the PWM signal Pw is sampled and then held by 100% over one cycle period of the signal Pw until the next peak to demodulate the audio signal Ss. Consequently, the signal Ss possesses the filter characteristics of sin x/x, and a carrier point becomes a nul point, so that the signal component Sa is automatically eliminated. By this method, even when the frequency of the PWM signal Pw reproduced by hand-cuing is lowered as shown in the figure B, the audio signal Ss suppressed of noise by the signal component Sa can be obtained.

IPC: H03H9/05
Filed: 1989-06-26
Abstract: PURPOSE:To prevent electrostatic destruction and to incorporate a matching circuit by connecting a couple of bus bars opposite to each other via a resistance pattern/inductance pattern. CONSTITUTION:A couple of bus bars 2, 5 opposite to each other are made conductive with a resistance pattern 6 and/or inductance pattern as part of a matching circuit. Thus, the charge by the staticelectricity between the bus bars 2 and 5 and between comb-line electrodes 3 and 4 is prevented by conducting the bus bars through the resistance pattern 6. Moreover, a layer made of chromium or the like is used mostly for the lower layer of the comb- line electrodes 3 and 4, then the chromium layer is utilized for the resistance pattern 6 and integrated in a surface acoustic wave circuit on a substrate 1 altogether by the technology such as the photomechanical process. Thus, the charging of the resistance pattern 6 and/or inductance pattern due to the static electricity between the comb-line electrodes 3 and 4 is prevented and the resistance pattern 6 and/or inductance pattern is part of the matching circuit, then number of component is reduced.

Title: Ladder type crawler
Inventor: ONO YOSHIHIKO
IPC: B62D55/253
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To obtain excellent wet field traveling performance without damaging a cultivated bed, prevent mud clogging between fin-shaped parts and lower bearing pressure so as to levitate a machine body by forming lugs of a crawler into zigzag fin parts, and placing lug end parts, positioned inside on the opposite side to the zigzag fin parts on the inside of the width edge of a rubber elastic body. SOLUTION: One tip of each lug 4 is protruded zigzag from the edge of a rubber elastic body 1 to form a fin-shaped part 8, and the other end 9 of the lug 4 has cutout shape without reaching the edge of the rubber elastic body 1. Accordingly, mud clogging is hardly generated to the peripheral surface S of a rubber crawler on which the other end 9 of the lug 4 faces, which leads to the increase of tractive force. The weight of a machine body is uniformly dispersed by the presence of this peripheral surface S so as to reduce such a phenomenon that the machine body sinks underwater, and such a defect as to ruin a cultivated bed can be improved.
